Abstract: 1372595 Retroactive control of speed. GENERAL ELECTRIC CO 3 Feb 1972 [5 March 1971] 5190/72 Heading G3R [Also in Division H2] In the control of a polyphase induction motor 59 driving a crane wherein a desired speed and direction reference signal from potentiometer 41 is combined with an actual speed signal derived from tacho-generator 57 and limited in value to the forward bias voltage of either one of diodes 71, 73 thus limiting the rate of change of motor supply, frequency, to provide a difference signal which, via integrator or low pass circuit 49 controls the frequency and voltage of the motor supply, the difference signal is opposed by a signal from slip limit circuit 91 whenever the motor slip, in motoring or over-running mode, approaches pull-out, or runaway valves (N po ), Fig. 1, 2 (not shown), the motor thus being constrained always to operate between pull-out and runaway speeds. Slip limit circuitry, 91, see also Fig. 4 (not shown). Differential amplifier 93 receives as inputs, the outputs of integrator 49 and tacho 57 representing respectively the motor supply frequency and actual motor speed, and its output is fed to slip limit circuit 99, which, comprising high resistances (171, 172) and low resistances (173, 174) in a series chain, the latter two in series being shunted by diodes (177, 179) whose mutual connection forms the circuit output, provides no output until the "IR" drop in either one of resistances (173, 174) is overcome by the input signal to their common point, such a signal level corresponding to the attainment of pull-out, or runaway speeds. Control of motor supply voltage and frequency. Analogue pulse rate circuit 61 provides pulse trains whose frequency is proportional to integrator output voltage and whose phase sequence is defined by the polarity of the integrator output voltage and which are fed to reference circuit 63 receiving also an input from voltage control circuit 81, circuit 63 providing sine wave outputs whose amplitude is proportional to frequency, unless an output from compensation circuit 121, sensitive to the existence of high slip value provides a further input to amplifier 83, via either one of diodes 129, 132 for motoring or over-running respectively, to increase the amplitude to overexcite the motor 59. Cyclo-convertor 65 provides a corresponding polyphase supply to the motor. Alternative motor power supply, Fig. 5 (not shown). The integrator output is fed to an oscillator (203), whose ouptut frequency is proportional to its input voltage, the oscillator output being amplified to provide one motor phase, the other being provided by phase shifting the oscillator output by 90 degrees in unit (209) and then amplifying it. Voltage control circuit 81 controls the gain of amplifiers (207, 211).

Abstract: 642,839. Making sliding-clasp fastenings. SERVAL SLIDE FASTENERS, Inc. Feb. 24, 1948, No. 5461. Convention date, Nov. 1, 1940. [Classes 83 (ii) and 83 (iv)] Stamping; shearing.-A method of embossing a metal strip to form a string of connected elements for a sliding clasp fastener oomprises stamping one, or preferably a group of elements, between a pair of dies and maintaining constant the shape and the spacing of the elements by simultaneously repressing between similar dies a group of previously formed elements immediately in front of the element or group of elements being stamped. A press suitable for carrying out the invention comprises a bed-plate 44 supporting a stationary die-holder 83 and a head carrying a die-holder 48 reciprocated between guides 45 from a crankshaft 52. A known kind of strip feed device 60 is operated from the crank-shaft by linkage 64 to feed the work between the dies. The lower die holder carries a stamping die 86 with a line of upstanding projections 87 and a shearing die 91 with two groups of cutting edges 92, 93. The upper die holder carries a stamping die 68 with a line of depressions to co-operate with the projections 87 and with two groups of cutters 76, 78, the latter group being arranged to engage the work before the former group. After each operation of the press head, the strip is lifted clear of the lower dies by a spring- operated ejector rod 99 and is stripped from the upper dies by fixed members such as 106, 108 which overlie the edges of the strip. In operation, the strip is fed forward a distance equal to the length of a group of, say, four fastener elements at a time and while the portions 72a and 87a of the stamping dies are forming four new elements from the strip, the elements immediately in front are firmly pressed between the portions 72b and 87b to prevent any distortion of the previously formed elements due to a flow of metal resulting from the formation of the fresh elements. This arrangement also ensures accurate spacing of all the elements along the strip. After being stamped, the edges of the elements are cut as shown in Fig. 12 by the cutting dies 76 and 91, the other cutting die portion 78 engaging a previously cut portion of the strip and ensuring accurate spacing.

Abstract: 499,241. Electrodeposition of copper. LANGBEIN PFANHAUSER-WERKE AKT.- GES. Feb. 22, 1938, No. 5483. Convention date, Feb. 22, 1937. [Class 41] During the electrodeposition of copper on a rotating cylinder, the deposit is smoothed by an agate roller which is fed to and fro axially, the roller being mounted so as to be free to adjust its position relative to the cylinder and its direction of rolling automatically. The coated cylinders are etchable for use as printing rollers. In the apparatus shown, the roller 16 is mounted on a carriage which is reciprocated on a spindle 5 by means not shown, the feed being about one third of the total path for each revolution of the cylinder. The carriage comprises a slide 6 carrying an arm 8 in which is mounted a double bearing 9 rotatable about a bolt 10. In this bearing is mounted a rotatable spindle 13 carrying a fork 15 in which the roller 16 is mounted, the spindle 13 also being axially adjustable. The fork 15 is bent so that the axis of the spindle 13 is tangential to the roller ; tilting of the carriage by axial movement of the roller is thereby avoided. The arm 8 is loaded by weights 12 mounted on a bolt 11. The roller and its carriage may be swung away from the cylinder as shown at the right of the drawing. The roller 16 and the cylinder 4 are kept wetted by a sponge 18 supplied by a tube 17. The cylinder is rubbed by stationary stones 19 at the edges. The roller 16 comprises a cylindrical middle portion about 3 cms. wide, curving away for about 2 cms. on either side. The anodes 3 are mounted on holders 2. During the first third of the period of deposition the roller is unloaded ; it is then loaded with a weight of about 10 kg. After completion of the deposition the roller is passed several times over the rotating cylinder with the load increased to 20-30 kg. The current is then switched on for a short time in the reverse direction. During the last half-hour of deposition the current-density is reduced to half its original value.
